1. 16. Greenhouse gas emissions from compacted peat soil

   University essay from SLU/Dept. of Soil and Environment

   Author : Antonia Hartmann; [2021]
   Keywords : carbon dioxide; compression index; Peatland agriculture; recompression index; sand addition; soil compaction;

   Abstract : Cultivated peat soils are a main driver for CO2 and N2O emissions, while the gas fluxes are dependent on intrinsic soil properties and land use. Sand addition into peat soils might reduce greenhouse gas (GHG) emissions and enhance soil strength, and thus the ability to tolerate soil compaction. READ MORE

3. 17. Modelling of a compensated foundation in GeoSuite Settlement

   University essay from KTH/Jord- och bergmekanik

   Author : Linnea Hermansson; Rebecka Söderberg; [2020]
   Keywords : Compensated foundations; Load compensation; Lightweight material; Clay; Settlements; Creep; GeoSuite Settlement; Kompensationsgrundläggning; Lastkompensation; Lättfyllning; Lera; Sättningar; Krypning; GeoSuite Sättning;

   Abstract : The world today is constantly growing, creating a need of new roads and residential areas. New constructions lead to an increased load onto the soil, which can result in deformations when the soil layers underneath are compressed. To reduce the increased load on the soil, a compensated foundation can be used. READ MORE

4. 18. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Daiki Makii; [2020]
   Keywords : Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

   Abstract : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.

5. 19. Thermal Acoustic Flow inside an Ultrasound Resonator

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Enrico Corato; [2020]
   Keywords : Microfluidics; Ultrasound; Acoustofluidics; Thermal gradient; Thermoacoustic; Technology and Engineering;

   Abstract : This thesis aims at investigating the interaction between thermal gradients and acoustic fields in microfluidic devices. In the research branch of Acoustofluidics, which bridges together acoustics and fluid dynamics, inhomogeneity in the medium has gained great interest due to the novel physics behind and the potential in manipulating submicrometer particles.

6. 20. Acoustic Characterization of the Cellulose-coated Perfluorocarbon Droplets based on Phase Velocity Measurements

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Emma Lindroth; [2020]
   Keywords : Ultrasound; Droplets; Contrast agent; Cellulose; Perfluorocarbon; Acoustic characterization; Non-destructive evaluation; Phase velocity; Bulk modulus; Compressibility;

   Abstract : Today, microbubbles are one of the most commonly used ultrasound contrast agents, since their high compressibility results in a strongly scattered signal. Despite this advantage, microbubbles experience limitations by the decreased stability and large diameter. READ MORE
